The exact syntax of the -version output isn't well specified.  But there 
is a guideline here:- http://java.sun.com/j2se/versioning_naming.html

That suggests you might use:  1.6.0_0-b11-1ubuntu1 ??

Are you also modifying the value of the system property java.version ??

Another thought is the -version:string option which the java command 
uses to select from multiple versions.   Okay, sure, Ubuntu has its own 
alternatives mechanism, but you could also modify the handling of 
-version:string and how would your modified version string affect this?
